in a nutshell nmw, how do you record a compelling story about an individual using the camera lens without revealing enough about them so that someone can identify who they are and whack them?

is that clear enough? as far as i can tell you pointed me to articles in which identity is managed entirely differently, through things like IP addresses and handles, which as far as i can tell is not information revealed about a person during a camera session.

we're talking faces, unique physical attributes that serve as visual markers which, for the safety of the interviewee, need to be obscured or simply not revealed through camera techniques.

a simple, cheesey example is strong backlighting of a subjecy so that their facial features are in such strong shadow as to be impossible to discern.

I hope that helps you understand the situation better.
